The violin is a string instrument, usually with four strings tuned in perfect fifths. It is the smallest, highest-pitched member of the violin family of string instruments, which also includes the viola, cello, and double bass.
The violin is sometimes informally called a fiddle, regardless of the type of music played on it.
The violin is a very important part of South Indian classical music (Carnatic music). It is believed to have been introduced to the South Indian tradition by Baluswamy Dikshitar, the brother of Muthuswamy Dikshitar. Though primarily used as an accompaniment instrument, the violin has become popular as a solo instrument in the orchestration. Indian classical music uses a very different grip from the traditional European classical genre.
